COL1A1 Gene - Somatic Mutations in Cancer.

The gene view histogram is a graphical view of mutations across COL1A1. These mutations are displayed at the amino acid level across the full length of the gene by default. The COL1A1 mutation data are now in a new database. New data last added: 15 Febraury, 2008 Corrections and other changes 1 August, 2008 As far as possible, the mutations are reported according to current guidelines, though some old data still need to be re-formatted. It is a heterotrimer comprising two α1I chains and one α2I chain which are encoded by the unlinked loci COL1A1 and COL1A2 respectively. Mutations at these loci result primarily in the connective tissue disorders osteogenesis imperfecta and Ehlers-Danlos syndrome types VIIA and VIIB. The Human Gene Mutation Database. at the Institute of Medical Genetics in Cardiff.

Dalgleish 1997 described a mutation database for the COL1A1 and COL1A2 genes. Mutations in the COL1A2 gene appear to be very rare causes of type I osteogenesis imperfecta. Korkko et al. 1998 developed a method for analysis of the COL1A1 and COL1A2 genes in 15 patients with type I OI and found only COL1A1 mutations. They described their protocols for PCR amplification of the exon and. The diagram herein given presents the COL1A1/PDGFB chimerical protein encoded by the T94796 tumour-derived chimerical COL1A1/PDGFB cDNA sequence: A chimerical COL1A1/PDGFB cDNA sequence fusing COL1A1 exon 29 to PDGFB exon 2 was isolated from the DP T94796 tumour and stably transfected in the Chinese hamster lung fibroblastic cell line PS200 E.

Consistent with results obtained from Oncomine, a cancer microarray database and web-based data-mining platform, it was demonstrated that the expression of COL1A1 was significantly upregulated in CRC tissues and cell lines regardless of KRAS status. Pathogenic mutations in COL1A1 and COL1A2, the genes that encode the two subunits, cause a range of phenotypes including mild to lethal forms of osteogenesis imperfecta and a restricted set of. Jun 23, 2016 · Mutations in COL1A1 4395 bp, 52 exons and COL1A2 4101 bp, 52 exons genes are responsible for approximately 90% of all OI cases. Mutations in the CRTAP 1206 bp, 7 exons and LEPRE1 2892 bp, 15 exons genes are in the background of a rare milder form of osteogenesis imperfecta type VII, VIII.

OMIM Entry -120150 - COLLAGEN, TYPE I, ALPHA-1; COL1A1.

Apr 21, 2017 · This information comes from a database called the Human. is the most abundant form of collagen in the human body. Mutations in COL1A1 or COL1A2 lead to structural abnormalities in type I collagen molecules. This weakens tissues that are rich in type I collagen, such as the skin, bones, and tendons and causes the many signs and symptoms. The disease is caused by mutations affecting the gene represented in this entry. Disease description An autosomal dominant form of osteogenesis imperfecta, a connective tissue disorder characterized by low bone mass, bone fragility and susceptibility to fractures after minimal trauma. COL1A1 collagen, type I, alpha 1 is a protein-coding gene. Diseases associated with COL1A1 include ehlers-danlos syndrome, type vii, and oi type ii. GO annotations related to this gene include platelet-derived growth factor binding and identical protein binding. An important paralog of this gene is COL4A6. tion of COL1A1/2 mutations and compare them to other studied OI populations, percentage differences were used. Results Mutational analysis of the COL1A1/2 genes of Estonian OI patients highlighted OI causative mutations in 26 of 30 patients 86.67% Fig. 1a. The number of patients harboring COL1A1 mutations was 20 76.92%; COL1A2. Test Guide. Over 95% of the forms of OI lethal and non-lethal result from a single dominant mutation in either COL1A1 or COL1A2, the two genes that encode the chains of type I procollagen. The phenotype that results from the disease-causing variant is a consequence of the underlying mutation type and location in the alpha 1 or alpha 2 chain of type I procollagen.
